Piecewise Hereditary Algebras

Bulletin of the London Mathematical Society, 1988
Let A be a finite dimensional algebra (associative, with an identity) over an arbitrary field k, and let D b(A) denote the derived category of bounded complexes of finitely generated right A-modules (in the sense of \textit{J. I. Verdier} [Lect. Notes Math. 569, 262-311 (1977; Zbl 0407.18008)]). Following \textit{D. Happel} and \textit{C. M.

Piecewise constant and piecewise linear expansions

Computers & Chemistry, 1977
Abstract We consider certain complete, orthonormal systems of piecewise-constant functions which include the Haar and the Walsh system as special cases. Using the properties of these systems we generate and study certain complete systems which are piecewise linear.

Monotone Piecewise Bicubic Interpolation

SIAM Journal on Numerical Analysis, 1980
Given a set of monotone data values arranged over a rectangular grid, the authors present an algorithm that produces a \({\mathcal C}^ 1\) piecewise bicubic function which interpolates to the given data and which is monotone. Some sufficient conditions for monotonicity are translated to a system of linear inequalities, which is the basis of the ...
